+1 I think the prototype is close to the Si, and the regular sedan will look like a Legacy.If I had to venture a guess... the Si will most likely be more similar to the prototype in appearance, maybe add a spoiler. I seriously doubt they'd add a full width taillight (the hatch will have one however based on the patent images), let alone the 10th gen fake intakes, or the 10th gen coupe rear lower bumper garnish. I fully expect the Si to be a very very very toned down concept of sporty this time around, (spoiler, tasteful body kit, wheels), as well as the Type R (massive wing and maybe a body kit/additional functional vents).
I think a good example to look at, as the comparison has already been drawn, the visual differences between the Jetta and the GLI. Different wheels. Accessory spoiler. Very tasteful lower body kit/exterior garnishments. That's what we will most likely see on the civic vs the Si, with the Sport trim having most of the same minus the performance upgrades.+1 I think the prototype is close to the Si, and the regular sedan will look like a Legacy.
